PPR Equal Coupling

Product Overview

The PPR Equal Coupling is a socket fusion pipe fitting made from polypropylene random copolymer (PP-R), designed to connect two PPR pipes of the same diameter in compatible hot and cold water piping systems. Its straight-through configuration provides a practical solution for extending or repairing PPR pipeline runs while maintaining a continuous flow path.

The fitting uses socket fusion, where the external surfaces of the PPR pipes and the internal sockets of the fitting are heated and then joined together. After cooling, the pipe and fitting form an integrated connection with reliable sealing performance. The smooth internal surface of PP-R helps maintain efficient water flow and reduces the tendency for scale buildup during operation.

Product Description:

Applications

Hot and Cold Water Systems — for connecting same-diameter PPR pipes in compatible hot and cold water supply pipelines.

Residential Plumbing — for extending and connecting PPR pipe runs in domestic water distribution systems.

Commercial Building Plumbing — for water supply installations in apartments, hotels, schools, and other buildings.

Pipeline Repair and Extension — for joining compatible PPR pipes when extending or restoring pipeline sections.

Key Features

PP-R Construction — made from polypropylene random copolymer, providing good corrosion resistance, chemical resistance, and lightweight handling.

Equal-Diameter Connection — connects two PPR pipes of the same nominal diameter to maintain a continuous pipeline.

Socket Fusion Connection — both pipe ends are inserted into the fitting sockets and heat-fused to form an integrated connection after cooling.

Reliable Sealing — the fused joint provides strong connection integrity and helps reduce leakage risk when properly installed.

Smooth Internal Surface — provides low flow resistance and helps reduce scale buildup inside the fitting.

Temperature and Pressure Resistance — suitable for compatible PPR hot and cold water systems when matched with the appropriate pipe pressure rating.

Lightweight Installation — PP-R construction simplifies handling, transportation, and installation compared with conventional metal fittings.
